I don't know if Windows actively maps round bad memory (and in my case its only a single bit). However it could be the difference in distribution of kernel-mode structures. If windows keeps them all in one place but Linux keeps them all over memory it could make Linux more susceptible. After all corrupt memory in user-mode is never a problem - you just lose the one process. It would of had to been a kernel structure getting clobbered to cause the hang, I'm guessing a pageing request or something like that rather than a syscall. > As for the badmem tools I've never been able to get > them running nor have I really taken a hard run at it.

After spending a good hour on the phone to PC world who siad they can't diagnose the problem unless I'm running windows I swapped the sticks. Hopefully this should solve the problem.
